How to Judge Distance Using the Front of the Car?

[DelJoseph]

When following a car, mainly observe the tires of the vehicle ahead. Adjust your sitting position properly. When you look forward from inside the car and just see the tires of the car in front, the distance between you and the car ahead is approximately 2.9 meters. This distance is quite suitable for low-speed driving in urban areas, ensuring a reasonable reaction distance. During traffic jams, if you only focus on the tires, it's easy for others to cut in. Therefore, you should move forward slightly and mainly observe the lower edge of the bumper. This distance is usually about 2.2 meters, which is only half a car length, making it harder for others to cut in. Use the rearview mirror to check if the car body is parallel to the lane markings. If they are parallel, it means both the front of the car and the body are aligned. If not, minor adjustments are needed. However, it's important to note that convex mirrors, which bulge outward in the middle, are used to expand the field of view. As a result, when observing lane markings, they may appear wider at the front and narrower at the back. If the left front hood of the car intersects with the left lane line and the intersection point remains unchanged, it indicates the car body is aligned.
